For list questions, apply the rules one by one to eliminate answers.
This question is a bit different, because we can’t use the first four rules. They deal with the groups, friendship and liberty. This question is about majors.
The fifth rule eliminates D. P can’t be a geology major.
The sixth rule eliminates E. N has to be a geology major, not a history major.
Another rule is in the setup paragraph: there are two geology majors, two history majors and one journalism major.
A is wrong because it has two journalism majors.
B is wrong because it has three history majors.
C is CORRECT.
